Nursing Elites

1. What are the primary causes of respiratory acidosis?

• A. Hypoventilation and lung disease
• B. Hyperventilation and pneumonia
• C. Increased oxygen saturation and tachypnea
• D. Dehydration and hypoxia

Correct answer: A

Rationale: The correct answer is A: Hypoventilation and lung disease. Respiratory acidosis occurs when there is an accumulation of CO2 in the body due to inadequate ventilation. Hypoventilation, which reduces the elimination of CO2, and lung diseases that impair gas exchange are the primary causes. Choice B is incorrect because hyperventilation, not hypoventilation, leads to respiratory alkalosis, not acidosis. Choice C is incorrect because increased oxygen saturation and tachypnea do not directly cause respiratory acidosis. Choice D is incorrect as dehydration and hypoxia do not typically lead to respiratory acidosis.

2. What is the role of the nurse in the care of a patient with a pressure ulcer?

• A. Clean the wound and apply a protective dressing
• B. Assess the wound and reposition the patient frequently
• C. Apply pressure to the ulcer and monitor for signs of healing
• D. Provide pain relief and administer antibiotics as needed

Correct answer: B

Rationale: The correct answer is B: Assess the wound and reposition the patient frequently. When caring for a patient with a pressure ulcer, it is crucial for the nurse to assess the wound regularly to monitor its progress and prevent complications. Additionally, repositioning the patient frequently helps to relieve pressure on the affected area, prevent further damage, and promote healing. Choice A is incorrect because while cleaning the wound is important, applying a protective dressing is not the primary role of the nurse in managing a pressure ulcer. Choice C is incorrect as applying pressure to the ulcer is harmful, and monitoring for signs of healing should not involve applying pressure. Choice D is incorrect as providing pain relief and administering antibiotics may be necessary but are not the primary interventions for managing a pressure ulcer.

3. A nurse is preparing to perform a sterile dressing change. Which of the following actions should the nurse take when setting up the sterile field?

• A. Place the cap from the solution sterile side up on a clean surface.
• B. Open the outermost flap of the sterile kit away from the body.
• C. Place the sterile dressing within 1.25 cm (0.5 in) of the edge of the sterile field.
• D. Set up the sterile field 5 cm (2 in) above waist level.

Correct answer: A

Rationale: To maintain the sterility of the field, the nurse should place the cap from the solution sterile side up on a clean surface. This action helps prevent contamination. Choice B is incorrect because opening the outermost flap toward the body increases the risk of introducing contaminants onto the sterile field. Choice C is incorrect as the sterile dressing should be placed at least 2.5 cm (1 in) from the edge of the sterile field to prevent accidental contamination. Choice D is incorrect because setting up the sterile field above waist level could lead to inadvertent contact and compromise the field's sterility.

4. A nurse is providing teaching to an older adult client about methods to promote nighttime sleep. Which of the following instructions should the nurse include?

• A. Eat a light snack before bedtime.
• B. Stay in bed at least 1 hr if unable to fall asleep.
• C. Take a 1 hr nap during the day.
• D. Perform exercises prior to bedtime.

Correct answer: A

Rationale: The correct answer is to instruct the older adult client to eat a light snack before bedtime. This is beneficial as it helps prevent hunger, which can disrupt sleep. Choice B is incorrect as staying in bed for a prolonged time if unable to fall asleep can lead to frustration and worsen insomnia. Choice C is incorrect as taking a 1-hour nap during the day can interfere with the ability to fall asleep at night. Choice D is incorrect as performing exercises prior to bedtime can increase alertness and make it harder to fall asleep.

5. A nurse is administering lorazepam to a client who is scheduled for surgery within 1 hr. Which of the following actions should the nurse take after administering the medication?

• A. Keep the client awake
• B. Instruct the client not to get out of bed
• C. Encourage the client to drink fluids
• D. Encourage early ambulation

Correct answer: B

Rationale: The correct answer is to instruct the client not to get out of bed. Lorazepam is a sedative that can cause drowsiness and impair coordination. By instructing the client not to get out of bed, the nurse helps prevent falls or injuries that could occur due to the medication's sedative effects. Choice A is incorrect as keeping the client awake may not be necessary and could lead to unnecessary discomfort. Choice C is incorrect as encouraging the client to drink fluids is not directly related to the administration of lorazepam. Choice D is incorrect as early ambulation is not safe immediately after administering a sedative medication.
